After 2 weeks of excellent service (except for the lack of an afp daemon in the router) my 5 GHZ radio died.  Like all of the sudden while streaming through my iMac to my Apple TV, nothing.  I powered down and back on, several times.  Nothing.  No radio (signal) detected on the scanner.  The 2.4 GHZ signal actually increased from -51 db to -48 db.  I returned the router for a new one.

Now after 3 weeks the 5 GHz signal has suddenly dropped from a strong -58 db to a weak -88 db.  Noise is at -92 db.  Nothing changed.  No firmware upgrade.  No moving of any device.  Just the 5 GHz radio burning itself out! Again  8-(  I need the 5 GHz radio because of the crowd (11) at 2.4 GHz.  The interference is ferocious.

You think maybe 3rd time lucky?  Or does someone recommend another 5 GHz product, D-Link or otherwise?

• Link>What Firmware version is currently loaded?

Any other Wifi near by on 5Ghz?
What channel is it using currently on 5Ghz?
Streaming thru your iMac to your Apple TV? I presume this is WiFi and you using the iMac a media server?

Been using my 826L for the past 2 weeks on 5Ghz for xbox gaming. Been doing well here.

What Firmware version is currently loaded?
---> Originally stock 1.01.  Upgrade to 1.04 had no effect.  Pretty sure its a hardware problem.  But I wonder what is breaking.

Any other Wifi near by on 5Ghz?
---> No.  That is why I got 5 GHz and while it works it works GREAT.  Same net speed as the one wired computer.  (speedtest.net)

What channel is it using currently on 5Ghz?
---> Auto.  But doesn't matter.  When I manually set the channel I still do not see it in the scanner.  (5GHz is now dead, completely! 8-(

Streaming thru your iMac to your Apple TV? I presume this is WiFi and you [are] using the iMac [as] a media server?
---> Yes.  AirPlay Mirroring.  Should not affect life span of the 5 GHz radio, should it?

Been using my 826L for the past 2 weeks on 5Ghz for xbox gaming. Been doing well here.
---> Good to hear.  Let's see if you get past 3-4 weeks.  That seems to be the life span of the 5GHz radio.  As I said, the first worked also only about 2-3 weeks.

Since you seem to know the D-Link product mix like the back of your hand, any other 5GHz wireless routers you would recommend?  Or do I have to spend hours researching on my own?

Any chance you can take this router to a different location with different devices, say a friend for familys place just to see if the problem follows and test with different devices.

Can you set a manual channel 36 and see the radio at all?

I would not expect to see any failures using Apple products with this router. I have had my 826L for several months now. I'd have to go back and look to see when i got it exactly however both radios have been working well since I got it accept for the one issue on 5Ghz when I upgraded to v1.03 which i'm still wondering about. I have loaded v1.04 on it again and everything has been ok so far. D-Link is still sending me another 826L as they mentioned that there could be an HW issue when v1.03 was applied. They could not reproduce it there on there HW. I currently have a bridged DIR-865L and a DAP-1533 connected to the 5Ghz radio for 2 xboxes for gaming. Been working this radio pretty good.

I still feel this is an isolated issue possibly and the reason to see if you can take this unit to a different local, however if the 5Ghz is actually broke and not functional, then I wonder if your Apple devices could also be contributing to it's demise. I use a Mac Book Pro 2007 era on mine however I don't stream much thru it. I do that wired with a LAN file server. I just remembered that my roommate downstairs does streaming on his xbox over the 5ghz radio on one of the wireless adapters so it does get used for some video streaming. 

One other test you could try, you'll need to switch to 2.4Ghz, lower the power output of the radio from High to say Medium or try Low. Disable HT 20/40Mhz Co-existance option as well. Then attempt to stream with the Apple devices on 2.4Ghz. I'm wondering if there could be any failures here.

This is 2 same model routers that exhibited the same failure on 5Ghz with your devices. I presume there is a possible relation somewhere to the failure.

I have enjoyed my 826L for what it does and would recommended it being that this could be an isolated issue I think here. If your looking to remain with 5Ghz, you might try the 857, 827, 835, 868L, 855L or 836L. I do have the 857, 827 and 868L and all are very nice.

I'm going to pass this along to D-Link and see if we can get some review on this and some additional help.

Any status on this? Just curious.

OC-Carl returned the 826L directly to D-Link USA for review and inspection, and was upgraded a DIR-850L.

This issue is closed.
